pcb fabrication of A20-lime2

[flyingbaloon]

I am trying to get the pcb made from the gerber files provided for A20-olinuxino lime2 . The board thickness is 1.68mm and 8 layers . Many of the Online pcb manufacturers are supporting only 1.6mm thickness board . Could you please suggest me a fabrication house that can fabricate the board . Many thanks for the help .
